UNITED ,STATES PATENT 'O1-*rica ISAAO J. SALTZER, OF PRESOOTT, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO JOHN G. EOKERT, OF SAME PLACE.

SASH-,FASTENER SPECIFICATION forming part f Letters Patent NO. 297,953, dated April 29, 1884:.

Application filed February 14, 1884. (No model.)

citizen of the United States, and a resident of Prescott, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Fasteners;

andI do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which- Figure l is a perspective view of part of a window-casing from the inside, showing the arrangement -of my improved sash-fastener. Fig. 2 is a perspective view of one of the fasteners with its box removed from the windowcasing. Fig. 3 is a longitudinal sectional view of the same. Fig. 4 is a perspective view of the box and spring with the catches removed; and Fig. 5 is a perspective detail view of the two engaging catches, showing them 'separated from each other.

Similar letters of reference indi ate corresponding partsin all the'figures.

My invention has relation to sash fasteners or holders adapted for holding the upper and lower sashes of a window in their proper position in the window frame or casing; and it consists in the improved construction and combination of parts of a duplex catch or fastener, as hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings, A denotes the window-casing, which has the usual ways,

. B, for guiding the motion of the sashes, (shown at C.)

My improved fastener or holder is coniposed of a metallic box, D, having ears E, for fastening it by`screws or nails in the windowcasing, which is cut out or recessed for the insertion of the box. In the bottom of this box is placed a removable spring, F, bent to form a bulge, f, and at each end of the box is a cross-bar, G, upon which the catches are hung. The latter (two in number) consist each of a wedge-shaped piece of metal cut off or recessed at one side to form a wedge-shaped shoulder or offset. H denotes one of these pieces, and

directions `out of the box.

I the wedge-shaped shoulder or offset, the width or thickness of which is half of that of the body H. At one end isatransverse groove or recess, h, and the rounded under side, t', ofI the parts H I will', when the catches are prop- 5 5 erly inserted into the box, bear against the bulging part of spring F, as will appear more clearly by reference to Fig. 3 of the drawings. The corresponding catch is constructed in precisely the 'same manner, consisting of a 6oI wedge-shaped body, H', having a slightly- 4 rounded under side, i', bearing against the spring F, and having the wedge-shaped shoulder or offset I on one side, formed by cutting away one side ofthe part H to half its thickness. One of the catches is provided with a projection, Y K, having a finger-knob, L, for operating the device. The catches H I and H I are inserted into the box D by'slipping their hooked ends formed by the' transverse 7o grooves or recesses h and h around the crossbars 'G at opposite ends of the box, in which position` it will be seen that the projecting wedge-shaped end of one of the catches will bear against the wedge-shaped offset or shoulder I of the other catch, and vice versa, both the catches being actuated by the spring F, so as to cross and project their points in opposite rIhe stiles or sides of the sliding sashes are provided with plates 8o M, having projections or studs N, adapted to engage the projecting ends of the spring-actuated catches, and placed at such a distance apart as to readily engage both catches at the sametime. By depressing the knob or thumb- 8 5 piece.L,which projects to one side of the window-casing, so as to be readily accessible from the inside, the projecting catches will be depressed by compressing the bulging spring F,

so as to draw the points back from plate M 9o flush with the face ofthe box, and thereby permit the sash to move up or down. When, however, the thumb-piece L is let go, spring F lwill force the free ends of the catches, which cross each other, out of the box, so as to engage with their points the projections N on plate M. If the spring F should get broken or otherwise become useless, it may readily be removed by removing the two overlapping catches from the box, which may readily be loo done by slipping them off of the cross-bars G G, into which they may as readily be reinserted after a new spring has been placed in the bot tom ofthe box.

It will be seen that no screws or other fast enings are required for connecting the several parts of my improved sash-holder, and that its construction and combination of parts are sueh that it cannot readily get ont of order.

Having thus described my invention, I claim and desire so secure by Letters Patent of the United States- In a sash holder or fastener, the combination of the box having the cross-bars at opposite ends7 the removable bulging spring7 the two bolts or wedgeshaped catches hung removably upon the cross-bars at opposite ends ofthe box, crossing each other with their free ends and bearing against the spring at their point of intersection, and the thumb-lever projecting 2o from the side of one of the wedge-shaped Catches, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature 25 ILA
